Porous filtering ceramic membrane flat plate structure

Abstract

The invention relates to the field of flat plate ceramic membranes, in particular to a porous filtering ceramic membrane flat plate structure which comprises a base plate, an outer frame assembly is connected to the upper end of the base plate, a filtering assembly is connected to one end of the outer frame assembly, and a heating assembly is connected into the outer frame assembly. Due to arrangement of the filtering assembly, liquid entering the ceramic body can be divided into multiple strands to uniformly flow to the upper surface of the flat plate ceramic chip, and the filtering efficiency is improved under the action of water pressure; the cleanliness degree of the ceramic body is conveniently kept through arrangement of a filtering cavity and a collecting box, a ceramic body is conveniently used through the arrangement of the outer frame assembly, the outer frame assembly can protect the ceramic body in the outer side, disassembly and assembly of the ceramic body are facilitated, the filtering efficiency is kept, the temperature in the outer frame assembly can be increased when the air temperature is low by arranging the heating assembly, and the situation that the flat plate ceramic chip is damaged due to liquid freezing of the flat plate ceramic chip is avoided.

Description

technical field [0001] The invention relates to the field of flat ceramic membranes, in particular to a flat structure of a porous filter ceramic membrane. Background technique [0002] Ceramic membrane, also known as inorganic ceramic membrane, is an asymmetric membrane formed by inorganic ceramic materials through special process. Ceramic membrane is divided into two types: tubular ceramic membrane and flat ceramic membrane. The tube wall of tubular ceramic membrane is densely covered with micropores. Under pressure, the raw material liquid flows in the membrane tube or outside the membrane, small molecular substances or liquids permeate the membrane, and macromolecular substances or solids are intercepted by the membrane, so as to achieve the purposes of separation, concentration, purification and environmental protection. Pores, according to the different molecular diameters of the permeable substances within a certain range of membrane pore diameters, the permeability i...

Problems solved by technology

[0004] Usually, the liquid to be filtered is delivered to the interior of the ceramic membrane plate through a water pipe connected to the water pump. During the process, the water pressure at the connection with the interior of the ceramic membrane plate is relatively high, so that the impurities on the surface of the ceramic membrane inside the plate are blown away and covered on the surface. Its surface affects the filtering effect of the ceramic membrane and is not conducive to cleaning. Therefore, we propose a porous filter ceramic membrane flat plate structure
